article: One afternoon I toured an art museum while waiting for my husband to finish a business meeting.I was looking forward to a quiet view of the art works.
  A young couple viewing the paintings ahead of me chatted nonstop between themselves.I watched them a moment and decided the wife was doing all the talk.I admired the husband's patience for putting up with her continuous talk.Distracted by their noise,I moved on.
  I met with them several times as I moved through the different rooms of art.Each time I heard her constant burst of words,I moved away quickly.
  I was standing at the counter of the museum gift shop making a purchase when the couple came near to the exit.Before they left,the man reached into his pocket and pulled out a white object.He extended it into a long stick and then tapped his way into the coatroom to get his wife's jacket.
  "He's a brave man."The clerk at the counter said,"Most of us would give up if wewere blinded at such a young age.During his recovery he made a promise that his life wouldn't change.So ,as before,he and his wife come in whenever there's a new art show."
  "But what dose he get out of the art?"I asked,"He can't see."
  "Can't see?You're wrong.He sees a lot.More than you or I do."The clerk said,"His wife describes each painting so he can see it in his head."
  I learned something about patience,courage and love that day.I saw the patience of a young wife describing paintings to a person without sight and the courage of a husband who would not allow blindness to change his life.And I saw the love shared by two people as I watched this couple walk away hand in hand.
